to improvements in The invention relates a device forimparta permanent hair waver,

Y ing to the human. hair what" is commonly tailed description taken together-with the drawings which form a part of the specifica- J30 I which result is ll'lll ma soluhair on a known as a permanent wave. obtalnedby da'mpenlng the tron then windmg' wlsps of the mandrel and drying the hair in the presence of heat An object of the invention is to produce .a device of the character described-having means for reducing the temperature of the outer walls thereof inorder to avoid the ac:

cidental burning ofa person while manipulating the heater which it is necessary to maintain. at a more or less high temperature in order to obtain satisfactory results, while at the same-time maintaining a sufficient d e- V gree of heat within the heating tube to effectively dry the hairitherein and thereby impart to: it a fixed wave or curl.

A- further' object of the invention is to produce a device of the-character referred to -which. may

be struck from sheet metal; thus making. the production thereofin quantities economical of manufacture.

Further objects and advantages of the invention will appear from the following detion and in which: I Figure 1 IS a side elevation ofone of the cooperating tong like members showi g the fins on the cross-section thereof;

Figure 2 is a perspective of one of the *cooperating tong like members showing the inner; face of the crossssection' thereof,

Figure 3; do; a vertical section of the assembled members taken on line 3-3: cf Figure 1 showingfthe levers and their associate elements in full lines. i

For a. more complete and comprehensive understanding of the 'device reference 'may now be had to the drawings which like reference "characters indicate like; parts thlc'fliughout the several figures.- Reference characters 10 and-llindicate-the levers which. are pivotally relatedite each 7 other by a substantially ll-shaped leaf spring 1 12 which may be secured tothe levers in any 7 suitable manner as by rivets 13, the levers 10' construction are so formed b their lower current. Suitable insulation isprovided in- 11' may be graspedattheir upper endsan forcedinwardly thus forcing apart the semi the upper-portion of the levers '10 and 11 may a heating tube and the electric current passed and 11 being urged outwardly at their upper 1 ends and inwardly at their lower ends, by the action of the leaf spring 12. Levers 10 and. llvwhich are substantiallyv identical in portionsmas to-beof. semi-e1 iptical shape incross-section, thereby forming the outer walls of a substantially elliptical shaped tube in cross-section when assembled, which. tube is'open at both ends as, clearly shown in Figure 3. Securedto theouter' face of the bent lower portions of levers 10- and 11 are recessed sh.e'lls;14.-,;which recesses are open at their respective ends; thereby forming an air passage between the1shell and the outer wall i of the; tube for cooling the outer surface thereo-f.. Shells 14 are-provided with fins 15 which act as heat radiators andare naturally cooler at. their apexes by reasonof their ver tical thickness than the shell isat the base 0 of the rib, thereby further guarding against accidental burningby a person handling the heater. Intermediate the outer walls 16- and a the inner walls 18 of the heating element cas' ings of the tube, are electric heating elements 17 which extend outwardly of the tubeand are incased in insulating blocks 22 having sockets therein for receiving plugs19 ofelectrio wires 20 which lead to'a source of electric termediate the electric heating element and the walls 16 and 18 ofthe heating tube. 7 Wire 21 is for the purpose of connecting the heating elements 17 in. the electric circuit. After the hairs of a persons head'have been mandrel and alayer of suitable. fabric-placed over-the wound hair, when the levers-'10 and elliptical tube port ons-for the reception therebetween of'themandrel with the hair 7 wound therearound; whenthegpressurev on bereleased and the semi-elliptical portion forced together under the action-of theleaf 7' spring 12, thus enclosing the hair within the through the heating elements.

- dampened with a suitable solutionithey are- Having thus described my invention, what I claim is:

1. A permanent hair waver comprising two semi-elliptical hingedly related members, heating elements within the members and air chambers open at their respective ends intermediate the heating element and the outer surfaces of the semi-elliptical members.

2. A permanent hair waver comprising two semi-elliptical hingedly related members, having heating elements, and air passages open at their respective ends formed within the members and intermediate the elements and the outside surface of the semielliptical members.

3. A permanent hair waver comprising two semi-elliptical members hingcdl'y related to each other by means of a leaf spring, heating elements within the semi-elliptical members each of said members having an air passage open at its respective ends intermediate the heating elements and the outer surfaces of the semi-elliptical members.

4. A permanent hairwaver comprising a pair of cooperating levers, a leaf spring in terposed between the levers, semi-elliptical clamping members carried by the lower ends ofthe levers, shells having air passages therethrough atfixed to the outer faces of the lower portions of the levers, heating units intermediate the lower portions of the levers and the inner portions of the shells and fins extending from the outer surfaces of the shells.

5. A permanent hair waver comprising coacting arcuately formed pressure members, a heating element in each of said pressure members, an elongatedaperture passing longitudinally through said pressure members outwardly of said heating elements, a pair of spring related handles fixed to said pressure members and a flexible electric connection for said heating elements.

6. A permanent hair waver comprising a pair of heating elements enclosed in adjacent faces of coacting clamping members having concave adjacentfaces and convex, finned outer surface, an elongated aperture passing longitudinallythrough said clamping members intermediate the root of the fins and the heating element, handles integral with said clampin members and extending outwardly in transverse cooperating relation, and a substantially U shaped leaf spring fixed between said handles adapted to hingedly connect said handles and coincidently react to close said clamping members.

7. A permanent hair waver comprising coacting concave face clamping members, handles affixed thereto and transversely related to the axis thereof, said handles having fixed to their adjacent faces the opposite legs of a U- shaped leaf spring, with inwardly disposed bend, heating elements within and adjacent the faces of said clamping members, said clamping members having an elongated aperture passing longitudinally therethrough outwardly of said heating element, and a plurality of radiating fins formed on the outer surface of said clamping members, and means for connecting said heating elements in circuit with a source of electric power.
